I am not from NY either, so I'm not voting. But I must say that I like C the best.

But then, as O C pointed out, it's a bit boxy. (The golden ration is not called the golden ratio for nothing!) Ideally, I would like to see C with the red and yellow stripes resized so that they are not the same size. That would reduce some of the redundancy of the squares. (The red and white in a Robertson Hunting tartan demonstrate what I mean.)

That being said, I'd be proud to wear any of the three if I were from New York.

Excellent work, Brian.
